ATLANTA (MEDIA GENERAL) — Chick-fil-A launched a new mobile app Wednesday. To celebrate, the chain is giving away free chicken sandwiches. The catch? You have to download the new app, Chick-fil-A One.

The restaurant chain touts the app as a new way for customers to “experience Chick-fil-A.”

You can order on the app and pay in advance, skipping the line at the register, speeding up the process of waiting at the counter or drive-thru, according to a news release.

Menu items may be customized on the app, and food is prepared when customers “check in” at the restaurant.

“We know time is valuable, and we’re excited to offer this new convenience that will empower guests to order what they want, when they want it and exactly how they want it, all from their mobile device,” said Michael Lage, senior manager of digital experience for Chick-fil-A.

Any customer who downloads the app and creates a Chick-fil-A One account between June 1 and June 11 will receive an offer for a free chicken sandwich, spicy chicken sandwich or grilled chicken sandwich.
